The Shure ADX2FD/B87C is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers. It is ShowLink-enabled for automatic interference avoidance and real-time remote control of parameters. The transmitter also features Frequency Diversity

for seamless audio in even the most challenging RF environments.

The ADX2FD/B87C comes equipped with the Beta 87C condenser capsule designed to deliver an extremely smooth frequency response with extended high end for vocal performers and presenters. The capsule features a cardioid pick-up pattern that reduces rear- and off-axis background noise, helping to control feedback.

The transmitter operates in a single 146 MHz ultrawide UHF bandwidth. It provides up to 9 hours of operation on an SB920 rechargeable battery, with a transmission range up to 330' and a selectable 2/10/50mW RF output power.

With a durable, moisture-resistant, lightweight aluminum case, the ADX2FD/B87C transmitter delivers pristine audio quality, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement applications.
